How many particles are in 3.0 miles of aluminum

1.806 x 10∧24 particles

Explanation:

A mole is the amount of a substance that contains 6.02 x 10∧23 respective particles of that substance.

It means that 1 mole of Aluminium contain  6.02 x 10∧23 particles (Avogadro's Number).

∴ 3 moles of Aluminium would contain;

  3 x  6.02 x 10∧23  = 1.806 x 10∧24 particles
